Chemical and Geological Control on Surface Water within the Shade River Watershed in Southeastern Ohio  [PDF]
Prosper Gbolo, Dina L. López
Journal of Environmental Protection (JEP) , 2013, DOI: 10.4236/jep.2013.41001
Abstract:

The under-sampled middle and western branches of Shade River Watershed (SRW) in SE Ohio were investigated as part of the Ohio University—U.S. Environmental Protection Agency (EPA) STAR grant. This project was for monitoring the quality of watersheds in Ohio and classifying them according to their physical, chemical, and biological conditions. Water samples, as well as field parameters, were taken at twenty-two sites for chemical analyses. The ions analyzed included Ca, Mg, Na, Fe, Mn, Al, NO3, SO4, HCO3, and total PO4, while the field parameters measured included pH, dissolved oxygen (DO), total dissolved solids (TDS), electrical conductivity (EC), and alkalinity. To assess the water quality within the SRW, the analyzed ions and field parameters were compared to the USEPA criteria for the survival of aquatic life. Analytical results showed that the watershed is dominated by Ca-HCO3waters with DO, Fe, Mn, and PO4being the main causes of impairment within the streams. The relatively elevated concentrations of manganese and less extent iron may be associated with the local geology and the acidic nature of the soils. The high alkalinity and calcium concentrations are due to the limestone geology. The elevated phosphate concentration may be due to anthropogenic sources, fertilizers, or contributions from phosphorus-rich bedrock that differs geochemically from other areas.

Midwifery and Midwives Service Scheme: A Panacea for Improvement of Some Maternal and Neonatal Indices in Nigeria—A Brief Review  [PDF]
Prosper Adogu
Open Journal of Obstetrics and Gynecology (OJOG) , 2014, DOI: 10.4236/ojog.2014.47051
Abstract:

Introduction: Midwifery is the art of caring for women during childbearing. It is practiced throughout the world according to the norms, traditions and cultural practices found in each country. Maternal mortality in Nigeria is high but there are wide variations between the geopolitical zones of the country. Government has established the midwives service scheme (MSS) as part of efforts towards reversing the country’s unacceptably high maternal mortality trends. To improve these indices, the MSS in Nigeria engaged newly graduated unemployed and retired midwives to work temporarily in rural areas. The midwives are posted for twelve months to selected primary care facilities linked through a cluster model in which four such facilities with the capacity to provide basic essential obstetric care are clustered around a secondary care facility with the capacity to provide comprehensive emergency obstetric care. This brief review is an attempt at exploring the impact of the midwives service scheme on maternal and neonatal indices in Nigeria. Main content: The outcome of the MSS four years has been an improvement though unevenly and marginally, in these indices in the various geopolitical zones of Nigeria. Improvements have been noticed in maternal indices such as antenatal care attendance, women receiving two doses of tetanus toxoid and number of deliveries by skilled personnel. Also reduction in maternal and neonatal mortality has been observed over the years following introduction of the scheme. Major challenges however, include lack of essential drugs, poor accommodation facilities for MSS staff, irregular payment of their remuneration and lack of water/power supply to some designated facilities for the scheme. Recommendations and conclusions: It is therefore recommended that 24 hours availability of essential drugs at primary healthcare centers be maintained. This should happen in conjunction with regular payment of full entitlements and benefits and provision of secured, habitable and good accommodation for MSS staff. Finally, aggressive community mobilization should continue in order to engender community involvement and participation for sustainable program development.

Statistical analysis to characterize transport of nutrients in groundwater near an abandoned feedlot
P. Gbolo,P. Gerla
Hydrology and Earth System Sciences Discussions , 2013, DOI: 10.5194/hessd-10-1553-2013
Abstract: Surface water from a dugout pond and groundwater samples from seven shallow wells installed within an abandoned feedlot in northwestern Minnesota, USA. were analyzed for nutrients, ammonia, pH, temperature, and electrical conductivity (EC). In the study, multivariate statistical techniques including cluster and factor analyses were used to evaluate the interrelationship between the analyzed chemical species. The cluster and factor analyses grouped the analyzed chemical species into three different groupings or clusters based on the concentrations of the chemical species and physical parameters. From the factor analysis, approximately 78% of the variability in the factor 1 was caused by electrical conductivity (EC), ammonium (NH4+, total carbon (TC), and total phosphorus (TP), while within factor 2; approximately 82% of the variability was caused by temperature (T), pH, nitrate-nitrogen (NO3-N), and ammonium (NH4+. The contribution of nitrate-N and ammonium could be attributed to the high rate of denitrification and/or the dissimilatory nitrate reduction to ammonium. The change in the concentration of nutrients is attributed to redox conditions, temperature variation, and the movement of nutrients from manure.
High prevalence of syphilis among demobilized child soldiers in Eastern Congo: a cross-sectional study
Raphael Senga, Prosper Lutala
Conflict and Health , 2011, DOI: 10.1186/1752-1505-5-16
Abstract: Screening of syphilis using the rapid plasma reagin test and the Treponema pallidum hemagglutination assay was conducted in three transit sites of soldier reintegration in 2005. The Fisher Exact probability test was used to compare results.The prevalence of syphilis was found to be 3.4%, with almost equal distribution in respect to sex, location.Syphilis continues to be highly prevalent in demobilized child soldiers in Eastern Congo. Syphilis screening tests are recommended.Syphilis and to some extent other sexually transmitted infections (STIs) are a major public health issue for soldiers during periods of conflict. In the Democratic Republic of Congo (Congo), these have been exacerbated by widespread sexual violence. Child soldiers are particularly vulnerable due to several factors: incomplete maturation, low social conditions, use as sexual workers by superiors, and their promiscuous environment. During World Wars I and II and subsequent armed conflicts throughout the world, syphilis has played an unprecedented role in soldier morbidity [1]. The Congo, with almost two decades of armed conflicts, is characterized by widespread sexual violence [2,3]. In the Congo and other African countries, recruitment of child soldiers has been largely practiced despite its war-crime characterization as defined by the Rome Statute of the International Criminal Court [4].As a war nears its end, disarmament, demobilization, and reinsertion (DDR) of combatants is a compulsory post-conflict step. In the Congo, all child soldiers undergo this process, which allows soldiers who desire, or who are children, to return to civilian life. At the transit camp soldiers undergo compulsory syphilis testing. To prevent possible spread of the disease upon reintegration, those who test positive undergo treatment.Despite a number of studies dealing with syphilis prevalence in various contexts, to our knowledge, little is known about syphilis prevalence in demobilized soldiers, and particularly in c

Bayesian Analysis
Harrison B. Prosper
Physics , 2000,
Abstract: After making some general remarks, I consider two examples that illustrate the use of Bayesian Probability Theory. The first is a simple one, the physicist's favorite "toy," that provides a forum for a discussion of the key conceptual issue of Bayesian analysis: the assignment of prior probabilities. The other example illustrates the use of Bayesian ideas in the real world of experimental physics.
